2 Claims.

mounted for vertical movement in channels formed by the pulley stiles and stops and to remove the sash it is necessary to first remove the stops which requires such skill, time and care together with suitable tools to effect the removal without marring the finish that the average householder will not attempt the operation. On the other hand the inconvenience and difiiculties of cleaning, painting, repairing window panes and the like with windows of this type are Well known and indicate the necessity for easily removable sliding saSh windows. Further, doublehung windows overlap each other and thereby reduce the effective ventilating area encompassed by the frame, even when the windows are fully opened, approximately fifty per cent.

The present invention contemplates a window frame to which fixed and pivoting rail sections are secured to co-act with the sash for eflicient vertical sliding movement and lateral stability of the sash and to facilitate the removal of the sash from the window frame by means of the pivoting sections of the rails as will hereinafter be set forth in detail.

The principal object of the invention is to provide means to quickly and easily remove the sash from the window frame without the assistance of tools of any kind and to greatly reduce the possibility of marring the finish of the casing, frame or sash as a result of the removal. Another object of the invention, supplemental to the above, is to provide means to utilize the entire area encompassed by the window frame for ventilating purposes. Still another object of the invention is to facilitate the installation and removal of screens and storm Windows from within the room. Another object of the invention is to provide an attractive window of substantially the same appearance as the conventional type of sliding sash window of equivalent cost.

With the above noted and other objects which may appear as the description proceeds reference will be had to the accompanying drawings in which:

Figure 1 is an elevational view of a window constructed according to my invention.

Figure 2 is a longitudinal view through a window with the sashes in the closed position.

Figure 3 is a longitudinal view similar to Figure 2 with the sashes swung into the room for removal from the track.

Figure 4 is a fragmentary detailed view in perspective of the head and style configuration.

Figure 5 is a fragmentary vertical section through the head and style showing a detail of the pivotal rail.

Figure 6 is a fragmentary vertical section through the sill and style showing a detail of the fixed rail.

Figure 7 is a fragmentary perspective view of a sash showing the rail groove.

Referring more in detail to the drawings it will be seen that the invention consists of a conventional frame insofar as it is related to the casing or architrave and building construction to the end that it readily lends itself to present carpentry practices.

The frame may be formed of wood or metal of any height and width desired and consists of the usual head [0, stiles II and sill 12 in which the lower sash l 3 and upper sash [4 are mounted for vertical sliding movement.

The head I0 and stiles I I are formed in a series of steps when seen in cross section which provide channels for the sashes to slide in and form a stop for wind and rain comparable to thestops and parting strip used on conventional windows. The first step in the head and stiles provides a channel for the lower sash l3. In the lower half of this channel rails l5 are imbedded in each stile II, the said rails extend up the stiles a distance less than the height of the sash for a purpose to be hereinafter explained. A rail I6 is imbedded in the sill [2 in alignment with the stile rails l5 thus forming a U-shaped fixed rail or guide on the lower half of the frame which engages in grooves l'l formed in the full length of the sash stiles and lower sash rail. Rails I8 are mounted for pivotal movement at their upper extremity to each stile in alignment with the fixed rails I5. I prefer to secure the pivotal rails l8 to the stile by means of a threaded bolt l9 disposed at right angles to the rail which passes through an orifice in the style and is secured thereto by the nut 20. The said pivotal rail extends downward to the fixed rail l5 and, as opposed to the fixed rail is capable of carrying the sash free of the said fixed rail.

From the foregoing it will be seen that the lower sash I3 is slidable on and guided and retained by the fixed rails l5, l5 and I6 and the pivotal rails l8, l8 and that, with the exception of the uppermost position, the sash is always in engagement with the fixed rails l5, l5. In the uppermost position the sash I3 is free of the fixed rails and may be swung into the room on the rails 18 which pivot'at I9 and then slide oil. the

rails for complete removal from the frame as seen particularly in Figure 3.

Referring now to the upper sash it, it is mounted for sliding movement in the second step of the head and stiles l l and is therefore narrower than the lower sash by the total depth of the step on each stile II and shorter than the lower sash by the depth of the step on the head IE] or more particularly the upper sash is of a width to pass between the fixed rails 15.

In the upper half of the second step or channel, rails 2| are imbedded in each stile II a distance less than the length of the upper sash and a rail 22 is imbedded in the head 10 of the frame in alignment with th rails 21. Pivotal rails 23 mounted at their lower extremity to the stiles H are aligned with the fixed rails and as opposed thereto are capable of carrying the upper sash free of the fixed rails. Thus the upper sash I6 is slidable on; :guided and retained by the fixed rails 21,2! and 22 and the pivotal rails 23, 23 by means of the Loo-acting groove H formed in the full length of the sashstiles and upper sash rail, in exactly the same manner as that described in greater detail with regard to the lower sash [3 but in. opposed relationship therefore. To remove the upper sash it is moved to the lowermost position :on the pivotal rails 23 and then swung into the room as the rails pivot on 19 and finally slid freeof the rails 23 for complete removal from the frame as illustrated in'Figure 3.

Toreplace the sashes the upper sash [:3 is slid onto the rails 23, pivoted into the vertical position and raised onto the fixed rails 2 I; the lower sash I3 is slid onto the pivotal rails i8, swung into the vertical position in the channel and lowered onto the fixed rails IS.

The third step in the head ID and stiles ll provides a parting strip 2 between the sashes l3 and I4 and the screen or storm window 25, and terminates at the outer step which forms a weather stop for the storm window. As seen most clearly in the cross sections in Figure 4 the outer step increases in sizecomparable to the second step. The storm window 25 is secured by means of a hook and eye 26 or other device common to the art.

, From the foregoing it will be seen that I have provided a window of thesliding sash type which operates efficiently and may be easily and quickly removed from the fram without recourse to tools of any kind to attain the objects hereinbefore set forth.

What I claim is:

l. A window frame and sash construction comprising a frame formed of vertical side members, a head and a sill, said side members and head having stepped inner faces, upper and lower sashes engageable in adjacent steps, a vertically disposed guide bar fixedly disposed in each step adjacent top and bottom ends respectively thereof and having a length less than the length of a sash, each sash having a vertical groove in the stiles thereof within which said guide bar loosely engages, a'ndasecond guide bar in each step ivotallysecured at one end to a side member at the end opposite from the fixed bar of said respective step and normally aligning with said fixed bar, said second bar being longer than the sash stile and providing :a means whereby said sashes may be swung outwardly at opposite'ends of said frame when move'd'out of engagement with said fixed guide.

2. A'window frame and-sashconstruction comprising a frame formed of vertical side members, a head and 'a sill, said side members and .head having stepped inner faces, upper and lower sashes engageable in adjacent steps, a vertically disposed :guide bar fixedl disposed in eachstep adjacent top and bottom'ends respectively thereof and having a length less than the length of a sash, each sash having a vertical groove in the stiles thereof within which saidv guide barloosely engages, a horizontal bar fixed to andprojecting upwardly from said'sill :in the vertical plane of said fixed bar, one of said sashes having agroove in the .-lower rail to "receive said horizontal bar, and a'second guide bar in eachstep :pivo'tally secured at one end to a side member at the end opposite from the fixed .bar of said respective step and 'normally aligning with said fixed 'bar, said second bar ibeing longer than the sash stile and providing a means whereby said sashes may be swung outwardly .at -'opposite ends of said frame when moved out of engagement with said fixed-guide.
